The survey ship HMS Echo is in the Indian Ocean, where the Australian prime minister said a satellite had detected objects including a 24-metre (79-feet) long piece of debris.
The ship is designed to collect ocean data to support submarine and amphibious operations and is equipped with a survey motor boat and a contingent of Royal Marines.
Malaysian Transport Minister Hishammuddin Hussein described the debris as a "credible lead".
A Norwegian merchant ship on Thursday became the first vessel to reach the area where the debris was spotted, about 2,500 kilometres (1,553 miles) southwest of Perth.
Ships and aircraft from a host of countries have been deployed in the search along two corridors stretching from the southern Indian Ocean to South and Central Asia.
